    07 GMC Sierra Classic - Blower Motor Wouldn't Turn Off With Ignition and No Blower Speed Variability
    Vehicle: 2007 GMC Sierra Classic 1500 SLT.Issue: When I turned off the vehicle one cold morning, the blower that blew heat in the cabin didn't turn off. I also lost variable blower speed settings and the air would only blow at one constant speed.Temporary Fix: Pull the fuse in the fuse box under the hood to turn off the blower/heat, and replace to get blower/heat.Fix: After doing some research, I purchased this part as a replacement for my suspected failing resistor. I took my old resistor apart and didn't see any signs of failure. It took me about 45 min to install the new part. The small connector plugged right into my OEM blower motor and I solder spliced the other 3 wires into the 3-wire connector that hooked up to the old one. Red to red, black to black, purple to purple. Fixed my problem.Also attached the instructions that came with the part if anyone needs it. I just read the pin configuration from the old to new connector to ensure I was connecting it properly. It also came with 2 mounting screws and a spacer pad (that I didn't need to use in my situation).I have the ATC (Automatic temperature control unit that looks like this...

    5.0 out of 5 stars Blower motor working intermittently?
    Reviewed in the United States on July 29, 2023
    Verified Purchase
    If you're looking at this, there is a good chance that your HVAC blower is either not working at all, or is working off and on whenever it feels like it. Mine was, and I mistakenly thought it was the climate control unit on the dash. Nope, that wasn't it, and almost $300 wasted. Took at look at University of YouTube, and they symptoms matched this resistor being bad. I placed my order, and it was waiting on my doorstep by 8am the next morning! Thanks Amazon. Took it out to my Suburban, and started the replacemant. A half an hour later I was done, and my AC was working perfectly again! Drove around all afternoon running errands, and it appears to be fixed.

    5.0 out of 5 stars I followed the recommendation on here to use butt splices and they did the job just fine. If you have a soldering iron
    Reviewed in the United States on January 3, 2016
    Verified Purchase
    My 2006 Chevy Silverado had a condition where the fan would stay on even with the key off and was completely unresponsive when I tried to manually control it with the buttons on the dash. After some quick googling I came to the determination that the blower control module was the problem. This thing is a piece of cake to get to in my truck, you have to remove the blower fan underneath the front right dash and then you can get the module out. Once you have the module out you'll need to splice some wires to be able to install the new module. I followed the recommendation on here to use butt splices and they did the job just fine. If you have a soldering iron, you could use that as well with some shrink wrap. This auto repair is very simply, just take your time and follow the instructions... If you can change your oil, you can change out this module and save yourself a couple hundred bucks by not going into the dealership.

    I've had this module on my truck for over a year now and have had absolutely zero problems with my blower fan. Good product!!!!

    Worked fine, instructions are decent. Also, consult YouTube. Be prepared to do 3 electrical connections. I used those shrinktube w/ solder butt connectors.

    If you choose to pull out the blower motor, be careful as the plastic is brittle in these 20ish year old vehicles. Definitely snapped off my mounting tabs, not sure how it's still up there but it is... lol

    It worked great for 15 months. Original one lasted 15 years. Found the replacement part failed because of a water leak from the windshield. Bought another one and it works great. Changed rating to 5 star.
    Additional notes:
    Put a second one in after the first failed after 15 months. Works fine although it is odd that the module came in a plain paper bag. I would guess, GM does not use plain paper lunch bags. One thing to note, I choose this part again, since I did try less expensive non GM ones and the fan/blower speed control does not work as well. The fan speed does not always turn on at the low speeds for the non-OEM modules and they sometimes stop running at the low speeds.

    4.0 out of 5 stars I now have a great HACK too speed up the instalation of this part. ( I highly recommend this )
    Reviewed in the United States on August 26, 2020
    Verified Purchase
    The reason I installed this part on my 2006 Chevy 2500HD was the controls for my climate control would not respond to input and would not power up or down and the fan motor would not shut off even when the key was removed. I can not vouch for the parts longevity because I just installed it yesterday. The hardest part of the installation was removing the power connector plug from the back of the fan motor. Seeing that you already have to use 3 butt connectors for the 3 wires that go to the new Mod. controller plug. I highly recommend my hack which is too just cut the two purple wires that go to the back of the fan motor its just 2 more wire butt connectors one wire has a white stripe so you don't cross connect them. If I would've done this the installation would've only taken me literally 10 minutes as I fought that damn fan motor connector plug for 25+ minutes.

    I also found out that you can also remove the fan motor on my 06 2500 hd with no tools as its just a clip and a twist, go figure that I found this out after I was done installing this part. I also highly recommend buying some heat shrink tubing to cover the butt connectors and make the install look much more professional than electrical tape.

    For the life of me I do not understand why this part does not come with the butt connectors crimped one end of the 3 wires and 3 pieces of heat shrink tubing included in the package.

    All in all the installation was easy I'd say a 4 out of 10 on the difficulty scale, it would be a 2 out of 10 if they instructed you to cut the 2 fan motor wires or how to drop the fan motor to get to the damn power connector in the back of the fan motor.

    The climate control works great again and the part fixed the problems that I mentioned above 100%.

    This is not an OME part but it appears to be an upgraded part over the OME part, I guess we shall see how long it holds up.

    Good luck, "you can do it".

    I used this to replace the blower control module in my 2006 silverado. It has the ATC option. I had to cut the 3 wire plug off my truck, and then wire this in place. Module fit perfectly where the old one came out. My AC blower works now! All settings and all speeds work exactly as they should. Inexpensive fix.

    *I'd recommend removing the 40A fuse for the blower motor before modifying the wires, otherwise you could end up popping it, and its not a typical blade fuse.

    I have 2 photos, one of the module I replaced and the module I received. If you have the 3 pin connector, this is the way to use a AC Delco part as a replacement instead of the replacement 3 pin modules you buy on ebay. Very simple repair.

    The heat on my 2003 GMC Sierra kept cutting out randomly until one day it completely stopped working and it was not my blower. This part worked amazing and have had no issues since. Easy to instal if you are comfortable connecting a couple wires.

    Started my truck up one morning to find that my blower fan was suddenly going full-tilt regardless of HVAC settings, and would persist even with the truck turned off completely. Spent a few days having to remove a fuse every time I parked my truck while I waited for this part. Battery would have surely died otherwise.

    Installation is a bit of a pain, but that's just because of the cramped location of the part. Any work behind the passenger side kicker-panel is always a PITA. I wish the new part was just plug-&-play and didn't require any wire-splicing, but it is what it is.

    A couple months later and the part is still working fine though. Considering what a hassle it becomes when the BCM goes bad, I would recommend spending the few extra bucks on the ACDelco part instead of a cheaper off-brand version.

    This is the correct part if you have automatic HVAC controls (RPO code CJ2, HVAC controller has a digital screen and dual-zone controls). If you have manual HVAC controls, you'll instead need a similar (and much cheaper, lucky you) part called a Blower Motor Resistor.

    Product is exactly as described. Install was super easy, and took less than an hour.
